s claims. (ci. '1v-.5)

The present invention relates generally to devices for scaling sh. More particularly the invention relates to that type of sh scaling device which is `designed to .be manipulated manually I and comprises (l) Aa tubular handle; (2) a shaft which extends longitudinally through, and is journalled in, a bushing in the handle and is adapted to be driven from an electric motor or like source of power by means of a flexible shaft;

and (3) a cylindrical rotor which is secured xedly to one end of the shaft and embodies radially extending projections on the periphery thereof for effecting scaling of the fish upon drive ofthe shaft by the motor.

One object of the invention is to provide a fish scaling device of this type in which the radially extending projections on the periphery of the rotor are of such design and construction that they cannot injure the users hands when brought into contact therewith, and serve to effect a quick and efficient scaling of a fish without tearing, gouging or abrading in any way the flesh of the sh. In general, these projections on the rotor are polygonal in conformation and have the leading portions thereof cut away to form flat faces which are adapted, when the rotor is brought into contact with the'sh scales, to scrape the scales oil? the skin of the fish to which the device is applied.

Another object of the invention is to provide a sh scaling device -of the type under consideration which is generally of new and improved construction, may be manufactured at a low and reasonable cost and is safer and more eicient in operation than previously designed devices of the same general character.

Other objects of the invention and the various advantages and characteristics of the present construction will be apparent from a consideration of the following detailed description.

The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by the claims at th conclusion hereof.

In the drawing which accompanies and forms a part of this specification or disclosure .and in which like numerals of reference denote corresponding parts throughout the several views:

Figure 1 is a View, partly in side elevation and partly in section, of a fish scaling device embodying the invention;

Figure 2` is a longitudinal section taken on the' Figure 3 is an enlarged transverse sectional view taken on the line 3--3' of Figure 1; and

Figure 4 is a view of a modified form of rotor, parts being shown in sections and parts being shown in elevations.

The device which is shown in Figures 1, 2 and 3' of the drawing is designed for use in connection with the scaling of fish and comprisesy a handle 4, a shaft 5 andv ametallic', hollow, cylindrical rotor 6. The handle 4is of tubular construction and fits around an elongated bushing 7. The latter is secured against rotation rela-- tively tojthe" handle in any suitable manner, and is provided at one end thereof with an externally threaded stern' 8. A1 nut `9 is connected to the stem and supportsV a substantially cylindrical guard 10. This guardfis'- provided with a pair of laterally spaced, longitudinally eitending slots 11 and 12'Sand' embodies at one end thereof an integral collar 13; The latter fits around theV4 75 nut 9 and is secured in place; by means of a set screw 14 which passes through a ,transverse hole 1'5 in the collarlancl bears, against'the periphery ofthenutfla l Y The shaft 5 extends through and is journalled in the bushing '7k and is arranged so that one` end thereof extends through a central hole opening in the nut 9 and projectslinto the space within the guard 10. The other end of the shaft is adapted to be connected by a flexible shaft .(notshovvn)y to' av motor or like' source of power for driving-purposes.

Therotor 6 is disposed within and longitudinally of ythe casing 11`0 and embodies at one end thereof a cross wall 16.` It is coaxially positioned with respect to the shaft 5 and is adapted to be brought into contact with a sh by way ofthe slot 11 inthe' guard y10. The cross wall 16 embodies'a central bore 17Athrugh which extends the end ofthe shaft 5 that projects inte 95 the guard'. The rotor is connected xedly to the shaft 5` by means of'a set screw 18. The latter extends through a transverse opening 19 in the cross wall 16 and engages the shaft.

In addition to the 'orosswall 16, the rotor 6 comprises a plurality of projections 20. The latter are formed integrally with, and project outwardly from, the outer periphery oflthe'rotor andare adapted, upon' applicationof the device to a sh, to scrape or Stripthe scales from theskin of the fish.

In order to prevent damage to the users hands and to effect an eiicient scaling without tearing,` gouging or abrading in any Way the skin or flesh of the ssh to which the device is applied, the proj'ections 20 are polygonal in form and are arranged so that certain of the corners thereof extend lengthwise and transversely of the rotor. The leading portions of the projections, that is, the portions which face in the direction of rotation and first engage the fish scales, arecut away so as to form fiat rectangular faces 21 which extend parallel with the axis of the rotor. These faces 21 are adaptedduringrotation of the rotorby drive of the shaft 5, to slap against the scales ofthe fish to which the device is applied and to scrape or stripthem loose from the skin of the fish. They are substantially radial with respect to the axis of the rotor and form with the top faces of the projections comparatively -blunt edges 22. The latter, by virtue of their bluntness, scrap the skin of the fish but `do not tear, gouge orabrade it in any manner. The projections 20 are preferably arranged in rows which extendvlengthwiseof the rotorand'ithe projectionsof each lrow are preferably staggered with respect toA the projections of the contiguous rows. `The faces of the projections which adjoin and are at the sides of the faces 21 .extendfrearwardly and outwardly with respect to the latter and operate, during rotation-of the rotor, to.

produce a wedge action which tends to force the scales laterally to a certain extent and thus loosen them from the skin of the fish.

In scaling a fish with the device, `the rotor is brought into direciicontact with the scales of the fish by pushing the guardivlO of the device so that the slot 11 faces the fish. After'so poi sitioning the guard, the device; is moved back and forth lengthwiseof the fish and operates to` effect a complete scaling asthe result of the projections 20 being brought in rapid succes'-, sion against the scales. During rotation ofthe rotor; ,thev faces 21 of the projections slap against and loosen the scales, and the angled faces ad-v joining the facesr 21v wedge the scales loose from the skin-,of the, fish. As 4the device is moved.v

lengthwise yof the fish, the scales' which are knocked loose by, the projections' 20 are discharged through the slot 12, which serves as an in operation, as-,the result of the specific constructiony and formation of the projections 20 on the` rotor 6.

Therotor fwhich is shown in `Figure 4 of 'the drawing is the same as that exhibited in Figures 1, 2 and 3 of the drawing, except that it embodies two cross walls at its ends and the proj ections have the leading andtrailingportions cut away. As aresult of this arrangement, ity

is possible to reverse the rotor when the edges 'at one side of the projections become dull.

The invention is not to be understood as re-` stricted to the details set forth, since these may be modified within the scope of the appended claims, without departingfrom the spirit and scope ofthe invention.
